MA - Red-headed Woodpecker - 05/15

Saturday (05/15/10) would see us take a family visit up to the Lewis Track and Field training facility in by Eagle Brook School in Deerfield. Two evenings before that I'd heard a Red-headed Woodpecker calling from a small tract of woodland near the track and decided to go back in an attempt to get a sighting, and perhaps even an image.

On arrival we didn't hear any woodpeckers calling or drumming but patient waiting along a nearby powerline cut eventually produced one, then two Red-bellied Woodpeckers being hotly pursued by a Red-headed Woodpecker! A crazy 'back and forth' then ensued for some minutes to the point where sightings of Red-headed Woodpecker were so frequent that I felt sure two birds must be involved, but at no point did I have two Red-headed Woodpeckers in view at the same time.

This close association between the Red-bellied and Red-headed Woodpeckers was intriguing and by following them I was eventually led to a cavity high in a Sugar Maple. I saw a Red-headed Woodpecker enter the cavity, seemingly suggesting breeding - "brilliant", or so I thought! A minute or so later the Red-headed left the cavity, but the hole was still occupied, this time by a Red-belliedWoodpecker! Over the next ten minutes I watched amazed as both Red-headed and Red-bellied Woodpeckers entered and left the same cavity.

It was the first time I'd seen two different species of woodpecker attempting to occupy the same cavity but, after a little background reading, it would appear that the Red-headed may have been the aggressor. Apparently Red-headed can be aggressive towards Red-bellied (especially) and other species of woodpecker sometimes usurping them from nestholes and will also eat the eggs and nestlings of other bird species! Certainly, the size and positioning of the cavity would, in my experience, be more typical of Red-bellied Woodpecker so my assumption was (though I'm far from sure) that the Red-headed was indeed attempt to usurp this pair of Red-bellied from their cavity - not quite what I was expecting to find on a sunny Saturday morning in Western Massachusetts!

The Images

Many of the images on this blog have been digi-scoped using Canon Powershot compact digital cameras (mostly the A590) hand held against a Swarovski HD telescope. Images of birds in flight have been taken in a similar manner but through Leica Ultravid 8 x 42 binoculars. I've also experimented with a couple of the 'super-zoom' cameras, the Panasonic Lumix FZ40, and the earlier version of the same, the Panasonic Lumix FZ7.

Since November 2013 I've been trying out a Canon Rebel T3i with various Canon lenses, my first venture into DLSR bird photography.
